I T0 all whom 'it may concern.'

-Bes it known that I, FRANCIS LEROY Honsroor., a citizenof the UnitedStates, residing at Salt Lake City, inthe county of Salt ake and Stateof Utah, have invented .a new and useful Emergency Locking-Bolt bejarred loose and lock'the safe bythe closing of the door.

Another object of'my invention, is to' provide an emergency locking boltthat can be held firmly into place andv work automatically when the lockhas been broken into.

Another object of my invention Vis to provide an emergency locking boltthat vis cheap in construction and can be applied to any style of safeor vault door by unskilled labor.

Another object of my invention vis to provide an emergency locking boltthat can beI heldlirmly unlocked by a wire attached to the cap of thetu'mblers of the combination.

l/Vith these and other objects in View my invention consists of thefollowing novel construction and arrangements of parts, to behereinafter described and claimed, reference being had to the annexeddrawings forming part of this 'specilication'and to the figures ofreference marked thereon.

Figure 1 is a fragmentary vertical sectional view showing the inventionapplied to the door of the safe, ready for use'. Fig. 2 is a transversesectional view looking toward the door from the inside of the safe.

Fig. 3 is an enlarged detail of the invention showing the springcompressed Aand the de- -vice ready for use.

Fig. 4 is an enlarged detail of the invention showing the springexpanded and the bolt in the locked position. Fig. 5 is a detail of theplunger. Fig.

6 is a detail of the locking bolt. Fig. 7 is a detail of the cylinder oreasing. Fig. 8 is a ldetail of one style of loekmg bolt which is to beused Vinplace of the devices shown in Figs-5 and 6, when the bolt isplaced on the bottom of the door; Fig. 9 is a detail View of the lowerend` 6- of the casing 1.

Similar letters and numerals refer to like parts throughout the severalviews of the drawings. V

vA designates a fragmentary section of a combination lock C.

' 1 is the tubular casing.

2 is the spring.

3 is the plunger.

4 is the bolt.

rIghe -tubular casing 1, is swelled at the upper end 5 forming a taper..The lower end 6. being flanged inwardly' at 7, forming the hole 8through which passes the stem 3 of the plungeiz A hole 9 is drilled inthe tubular casing 1 near the upper end 5 into which is placed a leadball 10. A sticker 11 is placed over the hole 9` to prevent the ball 10from dropping out. The locking bolt 4 is. grooved at 14. In the lowerend of the` plunger stem 3 is a hole 12, the upper end having a head 13.

Having thus described the parts of myinvention I will endeavor toillustrate the op 15 the tubular casing 1 and into the tubular casing1,- I place the spring 2, the plunger -safe provided with a door Bcarrying thel 3, and the locking bolt 4. Now I take the wire 19 securingone end into the hole 12 located in -vthe end of the plunger 3, I nowsecure the other end firmly to a screw lovcated in the back of thecombination cas- .undertake to enter the safe by breaking through thedial of the combination lock by driving in the spindle which pushes offthe casing 20, thus releasing the tension on the wire 19 which allowsthe spring 2, to

expand and raise the plunger which pushes the bolt 4 into the hole 17 inthe door casing 18, thus locking vthe door'so it cannot be opened, asshown in Fig. 4. By the use of the wire 19 Vwhich is attached asdescribed it is impossible for the bolt to be jarred loose, or throwninto a locking position by the closing ofthe door or any other knownmeans of jarring, such as falling.

When the'bolt is in a locked position the ball 10 drops down into thegroove 14, in

the locking bolt 4 which will prevent the said bolt'4 from being pulleddown in case that the combination was blown out so that the .burglarcould reach in and secure a.v hold on the wire 19. He would be able topull y 'down the plunger, but the locking bolt 4 would still be retainedin the locking posi'- tion by the ball 10', as shown in Fig. 4. A

groove 23 is cut into the'side of the locking bolt 4 for the purposeofallowing the ball 10 to travel in when the bolt isl thrown into a lockedposition. As the ball 10vis a little larger than the clearance 24, itwill beimpossible for it to drop out of the hole 9 when the bolt is 'ina locked position. The

K ball is also prevented from being thrown kso out of the hole 9.by asticker 11 which isv placed over the hole.

After thebolt 4 has beenthrown into a locked'position and I wishto'iopen the door, I drill `ahole through the casing A and down throughthe filling until the drill reaches the bolt 4, now I remove the .drilland place in a pin and push the bolt 4 back into the casing 1, then thedoor will open as usual. The location of the bolt is taken bymeasurement by the party who places the bolt onto the safe.

Having thus described my invention, what I claim as vnew and desire tosecure by Letters Patent, is:v

' 1. A device of the character described comprising a tubular casing,the upper end there'oi1 being tapered, said casing provided with a holelocated near said tapered end, a ball Within said hole, a bolt withinsaid casing provided with a groove for receiving said ball when saidbolt is in locked position, a plunger within-said casing for operatingsaid bolt,rsaid casing having a hole in its lower end for receiving thestem on end for receiving the stem on said plunger,

a Wire secured to said stem and attached to the locking mechanism on thedoor, a hole in said door for receiving the tapered end of said tubularcasing, substantially as and for the purpose tset forth.
